Can anyone relate with the erratic bleeding? Health anxiety 😥

I have felt like I was in the perimenopause for about a year now. I am 43.5. I have had some irregular periods. Some missed periods and some early periods. All of a sudden this month I have had erratic bleeding. I had a period for about 12 days and then now maybe a day without blood and then a day with blood and it’s been like that for about 20 days. I’m also cramping a little bit I have health anxiety so please don’t comment if you’re going to make it any worse. I have absolutely convinced that I’m dying. I have two young children and this is absolutely killing me the thought of being ill. I have also seen some people say that this could be perimenopause. Can anybody relate?
